I think without reading the report this is a hard question to answer. But, I agree with reservations. In other words, job descriptors may-in-fact be eliminated, yet there are new descriptors. A thought is how many workers does there have to be for a job to be considered a job with a study. For instance, I don't think a TV repair person would be considered, even though they still exist. That is perhaps extreme but leads to service industry jobs are being eliminated today especially in the repair sectors.
As far as my job . . . yes, that has happened. A note: I changed career direction when seeing that coming. I once was an automotive machinist. It was once common up to about 2000(?) for a car to have a valve job or two and/or an engine rebuilt in a car's lifetime. At first, it was the local automotive machinist doing the work with opportunity for small business through about the 80's(?). Then the remanufacturer industry eliminated most of the local automotive machinist. Thus, fewer automotive machinists.
Next, engines are built better lasting upward to twice as long and not requiring valve jobs within that engine life. And, it is economically cheaper to replace with new rather than remanufactured when considering investment value. So, today remanufacturing is on a downward cycle, so fewer businesses doing that and fewer automotive machinist. Instead, that job descriptor is being replaced by a machinist probably much of it is automated since new is being used more and more. I could go on and on about jobs in the automotive field historically with its ebb flow.
